Adult Stem Cells vs. Embryonic Stem Cells

Embryonic stem cells have the ability to develop into almost every type of cell in the human bodyAdult stem cells may only develop into a limited

number of cell types.

Increase an understanding of how

diseases occur

if have “sick” cells, can watch them mature to

see what occurs.
